Students and teachers at Adams Elementary School were briefly evacuated to the playground Wednesday morning after smoke began coming from a break room, according to a school official.

The smoke was from a worn out motor on an air conditioning unit that pushed smoke into the room, Long Beach Fire Department spokesman Jake Heflin said.

“The evacuations took place as a precaution, but the school is returning to normal operations,” Long Beach Unified School District spokesman Chris Eftychiou said.

The incident lasted less than 30 minutes with no injuries and no major damage, according to Eftychiou. He said the school has returned to normal operations.
